ArcGIS Pro 3.2| |帮助归档 摘要 Polygon对象是由 x,y 坐标对的连接序列定义的闭合形状。 说明 在许多地理处理工作流中,您可能需要使用坐标和几何信息运行特定操作,但不一定想经历创建新(临时)要素类、使用光标填充要素类、使用要素类,然后删除临时要素类的过程。可以使用几何对象替代输入和输出,从而使地理处理变得更...
Calculate the percentage area of each classified area of the slope map. Open the attribute table of the polygon layer. Right-click the new field created in Step 3, and clickCalculate Field. TheCalculate Fieldwindow opens. ForInput Table, select the polygon layer. In this example, the polygon...
选择“System Toolboxes”→“Data Management Tools.tbx”→“Generalization”→“Eliminate Polygon Part”。 其中,“Input Features”为需要补全空洞区域的图层,第二项为输出图层路径与名称,第三项为空洞区域补全的判断依据,其中“AREA”是指面积,也就是小于指定面积的部分都会被当作空洞区域补全;“PER...
area (Read Only) The area of a polygon feature. The area is zero for all other feature types. Double centroid (Read Only) The true centroid if it is within or on the feature; otherwise, it is the label point. Point extent (Read and Write) The extent of the geometry. Extent first...
我们在这里使用Reclassify命令进行打分分类,对坡度,距离道路距离,日照强度进行分类,统一度量衡为1-5,然后使用Weighted Overlay进行加权叠加运算,最后使用Reclassify功能选取4-5范围区间并使用Raster to Polygon进行格式转化,得到APPRO_Build.shp作...
首先在矿产地Point文件中打开Attribute Table,添加MineX,MineY两个数据列,数据格式为Double。而后选择乌克兰的这一处大理石矿,通过Calculate Geometry运算器,在Property一栏分别选取X Coordinate of Point,Y Coordinate of Point求得该点在 GCS_WGS_19...

在ArcGIS数据处理过程中，有时需要沿线把面要素分割开，可以使用高级编辑中的分割面（Cut Polygon）工具。
工具箱-Analysis Tools-Proximity-Create Thiessen Polygons。 2、使用工具 输入要素即为人口调查,自定义输出路径及名称,本例因为数据处理之前在环境中设置好了工作空间故默认即可,选择输出字段为All,以为后面要计算人口密度需要用。 设置环境中processing Extent为与道路图层相同。
Note: Certain fields are inherent fields of the feature class managed by the geodatabase, for example, in a polygon feature class, there are four fields that are unavailable for editing; OBJECTID, Shape, SHAPE_LENGTH, and SHAPE_AREA. The Calculate Geometry option is unavailable for these ...
